Projectile Motion Sim


http://phet.colorado.edu/en/simulation/projectile-motion

Find a pattern for projectiles launched at angles as you vary the launch angle between 70 degrees and 20 degrees above the horizontal.


As a result of working with the sim, be able to report back with...
1.  Something you thought you knew that was confirmed
2.  Something you did not know that you now know
3.  Something that you want to know

PMPM Video Tutorials

Hey gang,
  I'm a little under the weather, so enjoy this video introduction on problem solving with the projectile motion particle model.  This should be enough to help you get started on the projectile problem worksheet I had waiting for you on the cart this morning.  You only need to watch two segments, time 0:00 to 3:00 and time 7:00 to 12:40.  Then you can work on the sheets together/alone with your groupmates.

The angled launch stuff picks up around the 12:30 part of the first video, and then carries into this second video.

Projectile Motion Videos for Analysis

Use Logger Pro Video Analysis to Create Position v. Time and Velocity v. Time graphs for the horizontal and vertical motion of these projectiles.The meterstick for scaling is a 2 (TWO!) meter stick, so use that information accordingly....   You will need to find the slopes for any linear graphs (don't pretend to be taking the slope of a curve).  The motion is interesting once it leaves the hand of the thrower until just before it reaches the target/catcher.  Use the frame advance button to skip forward to the interesting part of the motion.

Just in case you've forgotten, here's the how to video for Logger Pro video analysis (for a different model, so your analysis will be different because you need X and Y position graphs and X and Y velocity graphs)...

Problem Solving with the Velocity Graph

Figuring out as much stuff as possible when you only know acceleration and change in position.
